DEVICE FOR MAKING AND FINISHING BOTTLE-NECKS- Specification of Letters Patent.

Patented Sept. 4, 1906.

To all whom it may concern:

Be it known that we, WILLIAM SHEPARD ,BREEDEN and HOWARD HANN BREEDEN,

citizens of the United States, and residents of Bradford, in the county of McKean and State of Pennsylvania, have invented a new and Improved Device for Making and Finishing Bottle-Necks, of which the following is a full, clear, and exact description.

Our invention relates to a machine for making and finishing the necks of glass blown jars, bottles, and homeopathic vials; and the purpose of the invention is to pro vide a machine in which a revoluble shaping and polishing tool is employed for that portion of the tube to be formed into the neck of a bottle, jar, or vial, and means for adjusting the bottle to the said tool, and also means for bringing the tool quickly into and out of action with relation to the neck of the bottle.

A further purpose of the invention is to provide a machine ofthe character mentioned which will comprise but few parts and which is simple and durable in construction and effective in operation, the machine being fully under the control of one individual.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, formin a part of this specification, in which simi ar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the machine, parts being broken away. Fig. 2 is a horizontal section taken practically on the line 2 2 of Fig. 1. Fig. 3 is a horizontal section taken substantially on the line 3 3 of Fig. 1, and Fig. 4 is a detail perspective view of one of the jaws for forming the neck of the bottle or vial.

A represents a portion of a table or a bench, and B the base of the machine, which is secured to the table or bench in any approved manner, and said base B is provided with a central aperture, surrounded by a collarlO, extending both above and below the base and through an opening in the said table, which collar serves as a bearing for the lower end of a vertical shaft 0. At one cornerportion of the base B another aperture is made, surcollar 11, and a corresponding aperture is preferably produced in the table or bench A. The guide-collar 11 receives the lower end of a supporting-rod 12, and said rod has play in the said collar 11 and may be of any desired height, being provided at its upper end with an inwardly-extending horizontal portion 12, and said rod 12 is adjustably secured in the said guide-collar 11 by means of a setscrew 13 or its equivalent.

Adjacent to the upper end of the shaft C a collar 14 is produced, which is preferably polygonal in general contour, and from the central portion of the upper end of the said shaft C where the collar 14 is located an upwardly-extending shaping-plug 15 is produced, adapted to enter the neck of the bottle and shape the same as the shaft C is re volved, the upper face of the mouth portion of the bottle resting at the same time upon the upper face of the collar 14, so that the said collar tends to shape the said upper portion of the neck ofthe bottle at its mouth, as is clearly shown in Fig. 1, the bottle being designated as 22. A block 16 is secured to the said shaft C a desired distance from the forming or shaping plug 15, the attachment being made through the medium of a setscrew 16 for example, and, as is particularly illustrated in Fig. 2, this block 16 is provided with vertical recesses or slots 17 in its side edges, and these slots have usually a tapering inner wall and are widest at their lower ends.

In connection with the block 16, carried by the shaft C, shaping-jaws D are employed, adapted to face one another, and each shaping-j aw is provided with a fin 18, longitudinally produced on its inner face at its lower portion. The fins of the said jaws D are made to enter the slots or recesses 17 and are pivoted therein by pins 19, passed through the fins 18 about centrally between the ends of the fins and through the lower corner portions of the slotted side sections of the block 16, asis shown in Figs. 1 and 2. The inner side edges of the fins 18 are beveled in direction of their ends in opposite directions from a central point, as is best shown in Fig. 4, and the apertures through which the pins 19 pass are produced in the said fins 18 adjacent to the said central portion of the said inner edges.

Each jaw D is provided with a head at its upper end, and each head at its inner face.

is provided with two stepped projectionsnamely, an upper projection 20 and a lower projection 20*, immediately following the upper one, the upper projections 20 of the said jaws being made to extend farther inward than the lower stepped projections 20 as is best shown in Fig. 1. As the shaft 0 is revolved the upper stepped projections 20 are brought into proper engagement with the outer face of the bottle-neck just below the mouth, as is shown by full lines in Fig. 1, so as to form or shape the neck properly at such point; but normally the u per ends of the said jaws D are made su ciently heavy to cause the said jaws to swing outward in opposite directions, swinging on their pivots 19, as is shown by dotted lines in Fig. 1, in which position the heads of the jaws clear the neck portion of the bottle 22.

In operation the bottle 22 is placed mouth down in the machine, and the body of the bottle is supported by a guide-head E. This guide-head is provided with upper and lower horizontal jaws 21, the jaws at the top and bottom being in pairs, and the space between the jaws of a pair is V-shaped, as is clearly shown in Fig. 3. This head is supported on the horizontal arm or member 12 of the supporting-rod 12, as is best shown in Fig. 3, the said arm or member 12 being passed through a suitable aperture 23, adjacent to one side of the said guide-head, and the head is held in adjustable position on the said member 12 by a set-screw 24 or its equivalent.

By reason of the adjustment of the supporting-rod 12 in the base of the machine and the adjustment of the guide-head E on said supporting-bar various-sized vials or bottles may be accommodated and successfully shaped and made onthe machine.

The head portions 20 of the jaws D are brought together when desired to shape the bottle-neck by forcing a cone 25 upwardly between the lower inclined edges of the fins 18 of the said jaws D, at which time the lower ends of the jaws are forced apart and their upper ends are consequently brought in direction of each other until stopped by the engagement of the lower stepped projections 20 with the shaping-collar 1 1.

A spring 26 is coiled around the shaft between the cone 25 and the block 16, on which the jaws D are pivoted, and the said cone, which is mounted to slide upon yet turn with the shaft 0, is provided with an annular groove 27, which receives projections from the spanner-arm 26 of a hand-lever 28, fulcrumed upon a suitable support 29, located on the base-plate B, preferably adjacent to the guide-collar 11, as is best shown in Fig. 2.

The shaft C is revolved by carrying a belt from any source of power over a pulley 30,

located, preferably, at the lower end of the shaft, as is clearly illustrated in Fig. 1.

This machine is exceedingly simple, it is durable, and will effectually shape the neck and mouth of any form of bottle, vial, or jar made of blown glass, it being understood that the glass is operated upon while hot.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1.
